Tewdur

Tewdur (855-885) was a Gliwissig general during the Welsh Rebellion of the 9th century. He commanded "The Britons' Revenge" army during the war with Wessex, taking over the remnants of King Owin of Gliwissig's Welsh army. In the autumn of 885 AD, he reoccupied the West Saxon-held Welsh city of Lann Ildut, but he was slain when the Saxons reconquered the city.
